GREEN SYNTHESIZED METALLIC NANOPARTICLES BY PLANT-BASED EXTRACTS AND THEIR FOOD APPLICATIONS: A REVIEW

Öz

Studies using plant-based extracts as reducing agents contribute to the synthesis of non-toxic, environmentally friendly, and economically viable metallic nanoparticles (MNPs) as an alternative to traditional chemical reduction procedures. While the synthesized nanostructures stand out with unique features depending on the metal type, they commonly share properties such as antimicrobial activity. This review presents a comprehensive overview of recent advances in green-synthesized MNPs using plant extracts. It highlights the latest research on their applications in food packaging, as food additives, and as antimicrobial agents targeting pathogens. Furthermore, this paper discusses the toxicological aspects, safety concerns, and limitations of green-synthesized MNPs. Most studies indicate that these on biosynthesized nanomaterials are safe for use as novel food ingredients; however, further in vitro and in vivo investigations are still required to fully establish their safety and efficacy.

BİTKİSEL EKSTRAKTLAR İLE YEŞİL SENTEZLENEN METALİK NANOPARTİKÜLLER VE BUNLARIN GIDA UYGULAMALARI: BİR DERLEME

Öz

Bitki bazlı ekstraktları indirgeyici ajan olarak kullanan çalışmalar, geleneksel kimyasal indirgeme prosedürlerine alternatif olarak toksik olmayan, çevre dostu ve ekonomik olarak uygulanabilir metalik nanopartiküllerin (MNP'ler) sentezlenmesine önemli anlamda katkı sağlamaktadır. Sentezlenen bu nanoyapılar, metal türüne bağlı olarak, genellikle antimikrobiyal ajanlar olarak görev yapma gibi ortak özelliğe sahiptirler. Bu derlemede, bitki bazlı ekstraktlar kullanılarak yeşil sentezlenen MNP'ler hakkında güncel çalışmalar kapsamlı bir şekilde açıklanmaktadır. Özellikle bu nanopartiküllerin gıda ambalajında ve patojenlere karşı gıda katkı maddesi ve antimikrobiyal ajan olarak kullanımıyla ilgili son çalışmalar derlenmiştir. Ayrıca, yeşil sentezlenmiş MNP'lerin toksikolojisi, güvenilirliği ve kullanımlarındaki sınırlamalar da tartışılmıştır. Biyosentezlenmiş MNP'ler üzerine yapılan çalışmaların önemli bir çoğunluğu, bu nanomalzemelerin yeni bir gıda bileşeni olarak kullanımının güvenilir olduğunu göstermekte olsa da bu nanopartiküllerin güvenli ve etkili kullanımları için daha fazla in vitro ve in vivo çalışmaya ihtiyaç duyulmaktadır.
